Abstract (technical / expert description):

Modern material lightweight constructions are characterized by the
substitution of conventional materials by high-strength steel and
aluminum alloys, as these enable a dimunition of the blank thickness due
to the high specific strength and thus contribute to the reduction of
CO2-emissions in vehicle operation. Since these high-strength
materials exhibit limited formability, the need for technologies that
enable the processing of these grades efficiently, increases. One
promising approach to manufacture complex, high-strength components is
forming under quenching conditions. This thermomechanical processing
method consists of a heat treatment and a quenching realized by the tool
during the forming process. Focus of this research project is the
processing of high-strength, precipitation-hardenable aluminum alloys,
which are characterized by a high yield strength and tensile strengths
of up to 600 MPa. The aim is to identify a robust process window for
these materials based on experimental and numerical data for the
manufacturing of high-strength components.
